To all 'ie/7mm it may; conce/rn Be it kno vn that L illumina GlinrinnnifnninoN, a-citizen of the United States-of America, resident ot'London, England, have invented certain new and useful improve-- ments in.llvpeVi-iting' Machines, o1 which the following; is a specification.

ll'y present invention relates especially lo paper feeding mechanism fortypewriting lo machines and its general object is to provide new andimproved mechanism of the char acter specied. lli/lore specificallystated, the object of the invention is to provide,improved means for l5:'ictuating a tally strip, said means being assoiifiatedf with otherpaper feeding means for continuously feeding another sheet.v Suchcontinuous feeding means is of a character commonly termed a platensweep; and in the 2o present instance l provide for actuating the ytally it'eed by the same operation which actuatcs the platen sweep, thetivo sets of t'eedi ing devices or mechanisms being' so related andoperatively connected that the operative connection may he dispensedwith or thrown out of, use readily whenever desired sothat either theplaten sweep or the tally feed may he actuated without aiiecting theother mechanism. yThe tally feed mechanisrnin 'the present constructionis not atl'ectedhy 4the -usual platen line spacii'ig' means which isprovided in addition 'to the platen sweep. To thc :diove and other endswhich will ."liereinaiter appear, iny invention consists 55 'in thefeatures of constructioin arrangements ot' parts and con'iliinations ofdevices hereinafter described and particularly pointed out in theclaims.

lriy invention will he more particularly 4G described in connection withthe accompanying drawings which illustrate the preferred torni ot' saidinvention applied to the carriage of a No. l0 Remington front-striketypeu'riting machine, and wherein.- d5

Said platen comprises a sheath tela-and a'Wooden core 1l, the core extendingsuhstantially full length but thesheath l, out short so as to permit a shorter fixed tion or platen l5 tohe' arranged at the rib" thereof. rv'lhe platen aor section l5 is designed to accommodate the tally strip and comprises afsheath l5 and ametal core l' which surrounds the core lill. The core l5 is connected byscrew and nut devices lo and l? with a loar i8 'iv'l'iicl'i is comprisedin a tally supporting frame, 'sa-id fraaie i1 ther including an arm 19integral with and extending rearward from the right-hand end of the bar18 and detachablf/ secu-red to the rod l2. The construction is such thatthe tally frame comprising the parts 1S and 19 is rigidly secured tothe' platen traine soci "l to said tally frame and through it to theplaten frame. The platens 14 and l5 ay be regarded as the sections ofdivided platen-which as a Whole comprises both the `rotarv--part 14 andthe xed part l5.

While I prefer inthe present `instance to' i employ the sheath l5n as a,striking-'surface or; platen proper, it may, if desired/` serve as-albacking for a. small, plate-like detach*- able striking surface as inniv prior applicadeemed necessary to, describe in any further detail theconstruction in this respect.l The to main platen 14 is provided withthe usual paper feeding devices comprising front and/ y rear feed orpressure rollers QO'and 2l' Ywhich coperate with said platen to advancethe paper when the platen is turned, These rollers, however, terminateshort of the lined platen. Devices are provided for turning the platen14n said devices including iingfer wheels secured to the parts orsections conf lll .ti li non si.

lor example, by wood screws 23 which screw into the ends of the woodencore 14b as The ratchet wheel 23 is arranged a the right-hand end of theplaten but has no connection with it, said platen and said ratchet wheelbeing' independent of each other. A roller detent (not disclosed)cooperates with the teeth of the ratchet is adapted to be turned by handoperated pawl and ratchet devices comprising a pawl 24 pivotallysupported on an arm 25 which turns on the right-hand part or axle 13 asa center. Said pawl is connected by a link 2G with a bell crank 27pivoted to the platen frame and connected in turn by a link 28 with acranlr arm 29 ixed to the rear end ot' a spring controlled rock shaft 80which turns in a housing 3l lined to the platen frame and terminates atits forward end in a line spacing handle or finger piece 32 which may beactuated to operate the pawl and cause the saine to turn the ratchetwheel 23 and platen 14 step-by-step for ordinary line spacing.

l'n addition means are provided for turning the platen 14 and advancingthe work sheet rapidi f and continuously', said means being preferablyplaten sweeping mecha' nism substantially like that disclosed in thepatent to Briggs and Ford, No. 955,942, granted April 2G, 1910 to whichreference may he' had for details of construction not herein disclosed.Some of the parts are differently arranged in the two constructions butin essentials they are 'the same. platen sweeping' mechanism comprises esegmental gear or toot-hed segment 33 provided with. an arm 34 whichterminates in a lateral finger piece The toothed or gear segment isarranged outside the right-hand end bar 6, and its operating arm isnormally substantially upright. Said segment is r1g1dly secured to a orbar 37 rigidly secured to the end bar 1.0 by screws 38. A

helical spring 39 surrounds the journal oi:A

the gear segment 33 and is secured at one end to said segment while itsopposite end is anchored to the armB', said spring restoring the segmentto normal position af Said segment constantly meshes with a pinion 40which is adapted to turn on the right-hand axle part 13 and has rigidlyconnected with it an arm or plate 41 at the outer end ot which ispivotally supported at 42 a spring pressed pawl 43 which is adapted toengage with the teeth of a ratchet wheel 44 ter operation.

(not shown) which surrounds its pivot and Said i stub shaft 36 whichisthat rigidly secured to 1 the axle 13. The pawl 43 houses av springvtends constantly to pressl it into, engagement with the ratchet wheel44. Said pawl and ratchet are, however, normally separated, the pawlbeing' held out by reason of its Contact with a liked lateral stop pin45 which is securedto a plate or arm 46 that.

may bear on the axle 13 and at its upper end is connected by a screw 47.with the outer end of the stub shaft 36 into which said screw isthreaded. The construction is such that the outer end ot' the stub shaftis additionally supported by the plate 4G which' is fixed by the screwlinger piece Sais pulled forward toactuate the toothed segment or rack33 the pinion 40 will be turned rearward, swinging the arm 41 rearward,causing the pawl 43 to move rearward and separate from the stop pin 45.rlhereupon the pawl spring (not shown) will cause said pawl to engagewith the ratchet wheel .44 which in turn will act on the platen 14 togive said platen a correspending turning movement. The extent of t iscontinuous turning movement of the platen depends on the setting ofadjustable stop devices, said stop devices comprising a lateral stop pin49, which bears loosely onthe platen axle 13 so that it may be turnedfreely thereon to adjust and variably locate the stop pin 48. rlhepositions of said ratchet wheel and of said stop pin 4S, however, arenormally fixed by a pawl or detent member50 which bears rotatably on thestop pin 45.

which engages' the ratchet wheel 49 while the upper end of said pawlabove its pivot bears normally against the front side of the head of thescrew 47.' The pawl is held in this position by a lll-shaped springplate 51 which is riveted or otherwise secured to the p awl and normallyembraces the head of the screw 47, thus ixing the pawl and the ratchet49. By pulling outward the rear arm ot the. springv plate 51, thelocking pa'wl 50 may be released, so that it may be thrown out of wheel49, enabling the ratchet wheel and stop 48 to be adjusted as desired.

The si'ning 78 normally mehreins the heed El() of fixed to and extending laterally rightward fromthe arm 3l. The lever is arranged in said slot and extends upward,terminating in a finger piece 82 which is in proximity to the fingerpiece 85 and may be manipulated concurrently therewith by the same handof the operator. Said finger piece normally stands away from the face otthe arm 3l as shown in full lines in Fig. 2. By pressing in lon thelinger piece and movingi it to the.

After the bill sheet is withdrawn, however, it isusually desired to sidvance the tally strip so as to position'itsuitably for the next total to be written and,v

as stated, this is preferably done when th'e fresh bill sheet is enteredand advanced continuously to position to receive the firstA However,-should it be desired for entry. any reason to advance the tallystrip inbetween these continuous advance movements due to .the operation of theplaten sweep,

this may be done by actuating'the finger piece ($9.
